[0005] 接近传感器设备可W被用来使能对相关的电子系统的控制。 [0005] W proximity sensor device can be used to enable the associated electronic control systems. 例如,接近传感器设备经常被用作比较大型的计算机系统的输入设备,包括:笔记本电脑和台式机。 For example, the proximity sensor devices are often used as an input device a relatively large computer system, comprising: laptops and desktops. 接近传感器设备也经常被用于较小的系统中,包括:如个人数字助理(PDAs)、远程控制运样的手持系统和无线电话和短信系统运样的通讯系统。 The proximity sensor devices are also frequently used in smaller systems, comprising: such as personal digital assistants (PDAs), handheld remote control sample transport system and radio telephone system and the sample transport messaging communication system. 接近传感器设备越来越多地被用到了媒体系统中,比如〔0、0¥0、1?3、视频或者其他媒体记录器或播放器。 The proximity sensor devices are increasingly being used in the media system, such as [0,0 ¥ 0,1? 3, video or other media recorder or player. 接近传感器设备可^是与其交互的计算系统的组成部分或外设。 ^ Proximity sensor device can be an integral part of the peripheral or interact with the computing system.

[0006] 过去,一些接近传感器已经被实施W额外的能力来检测并确定作用到传感器表面的力。 [0006] In the past, a number of additional proximity sensors have been implemented ability to detect and determine the role of W to a force sensor surface. 比如,通过从测量当手指按压表面时由于增加的接触面积而造成的增大的电容来估计作用力。 For example, when measured by the increased capacitance due to the increased contact area of ​​the finger pressing surface caused estimated force. 不幸的是,运些接近传感器的一些实施在使用运些技术估计作用力时只有有限的准确性。 Unfortunately, some proximity sensors shipped to some embodiments of these techniques when using transport is estimated force only limited accuracy. 因为受到质疑的准确性,运样的传感器通常只有有限的能力来使用运样被确定的力作为确定用户输入的基础。 Because challenged the accuracy of the sample transport sensors typically have limited ability to use the sample transport force is determined as a basis for user input. 运限制了接近传感器设备作为输入设备工作的灵活性。 Transport limits the proximity sensor device to work as an input device flexibility. 因此,存在对接近传感器设备改进的需求,尤其是接近传感器设备确定和响应于作用力的指示的能力。 Thus, there is an improved proximity sensor device's needs, especially capacity proximity sensor device in response to the determination and indication of force.

[0016] 本发明的实施例提供帮助提高设备可用性的设备和方法。 Example [0016] The present invention provides assistance apparatus and method for improving the availability of equipment. 具体说来,该设备和方法通过帮助对感应区中多个对象中每一个的位置信息和力信息的二者的确定来帮助提高用户界面功能性。 Specifically, the apparatus and method to help determine the position information and force information sensing region of each of the plurality of objects to help to improve both the user interface functionality.

[0017] 现在转到附图,图1是一个示例性电子系统100的框图,其W输入设备116操作。 [0017] Turning now to the drawings, FIG. 1 is a block diagram of an exemplary electronic system 100, the input device 116 W operation. 正如将在下文更详细地讨论的那样,输入设备116可W被实施为作为电子系统100的接口工作。 As will be discussed in greater detail below, the input device 116 W can be implemented to operate as an interface 100 of the electronic system. 输入设备116具有感应区118并且被实施为具有处理系统119。 The input device having a sensing region 118 and 116 is implemented with a processing system 119. 图1中没有示出的是适于感应在感应区118中的对象的感应电极的阵列。 FIG. 1 is not shown in the array of sensing electrodes adapted to sense an object in the sensing region 118. 图1中没有示出的还有禪合到感应区118下的表面W对作用到表面的力提供多个测量的多个力传感器。 The plurality of forces is not shown in FIG 1 there is bonded to the Zen sensing region 118 of the force acting on surface W surface provides a plurality of measurement sensors.

[0018] 输入设备116适于通过帮助响应于感应到的对象及运些对象作用的力的数据输入来提供用户界面功能性。 [0018] The input device 116 is adapted to provide user interface functionality with the help of the object in response to the sensed force and the operation of these objects a data input function. 具体说来,处理系统119被配置成对由感应区118中的传感器感应到的多个对象确定位置信息。 Specifically, the processing system 119 is configured to a plurality of objects sensed by the sensors in the sensing region 118 to determine location information. 然后此位置信息可W由系统100使用来提供广泛的用户界面功能性。 This location information may then W offers extensive user interface functionality 100 used by the system.

[0019] 此外,处理系统119被配置成从力传感器确定的力的位置信息和多个测量来为多个对象中的每一个确定力信息。 [0019] In addition, the processing system 119 is configured to determine each of the force information from the force sensor determines a position information and a plurality of power measurements of a plurality of objects. 此力信息然后可W也被系统100用来提供广泛的用户界面功能性。 This information can then force W can also be used to provide a wide range of the system 100 user interface functionality. 比如,通过响应于在感应区中多个对象中的每一个作用的力的不同级别提供不同的用户界面功能。 For example, in response to a function of providing different user interfaces in the different levels of force sensing region of each of a plurality of objects acting. 因此,输入设备116的处理系统119提供了对感应区中多个对象中每一个的位置信息和力信息二者进行确定的能力。 Thus, the input device 116, the processing system 119 provides the ability to both the position information and force information sensing region of each of the plurality of objects of determination. 运可W被用来帮助提高用户界面功能性,例如, 通过规定特定用户界面动作来响应多个不同对象的力的确定的指示。 W may be transported to help improve the user interface functionality, e.g., an indication of the force is determined in response to a plurality of different objects by specifying a particular user interface action.

[0020] 在一个实施例中,处理系统119被配置成基于多个对象中每一个的位置信息利用力的多个测量的叠加来确定多个对象中每一个的力信息。 [0020] In one embodiment, the processing system 119 is configured to overlay a plurality of objects based on the plurality of measurement information of each position is determined by the force of the force information of each of the plurality of objects. 此外,在本实施例的一个具体实施中,处理系统119被配置成利用伪逆矩阵技术确定多个对象中每一个的力信息。 Further, in a particular embodiment of the present embodiment, the processing system 119 is configured to determine power information of each of the plurality of objects using a pseudo inverse matrix technique.

[0021 ] 现在回到图1,如前所述,输入设备116包含一感应区118。 [0021] Returning now to FIG. 1, as described above, the input device 116 includes a sensing region 118. 输入设备116对一个或更多个输入对象(比如手指,笔尖等)的输入敏感,例如感应区118中输入对象114的位置。 The input device 116 inputs one or more input objects (such as a finger, pen, etc.) sensitive to, for example, the input position of the object 114 in the sensing region 118. 运里使用的"感应区"旨在广泛涵盖输入设备的上方,四周,里面和/或附近的任何空间,其中输入设备的传感器能检测用户输入。 Used in the operation "sensing area" is intended to encompass a wide range of input devices above, around, inside and / or any space nearby, wherein the input device sensor can detect a user input. 在常规的实施例中,输入设备的感应区从输入设备的传感器的表面沿一个或多个方向延伸到空间中,直到信噪比妨碍充分精确的对象检测。 In the conventional embodiment, the input device sensing area from the surface of the input device along the one or more sensor extending into the space until a sufficiently accurate SNR interfere object detection. 在一具体方向上感应区延伸的距离可能在不足一毫米,几毫米,几厘米或更多的级上,并且可能随使用的感应技术类型和要求的精度而显著变化。 In a particular direction extending from the sensing region may be less than one millimeter, a few millimeters, centimeters or more stages, and the type of sensor technology and accuracy requirements may be used with vary significantly. 因此,一些实施例可能需要与表面接触, 要么具有作用的压力要么不具有,而其他的一些又不需要。 Accordingly, some embodiments may require contact with the surface, or pressure has the effect of either does not have, and some others do not. 相应的,在不同的实施例中,特定感应区的尺寸、形状和位置可能有很大的差别。 Accordingly, in various embodiments, the size, shape and location of a particular sensing area may be very different.

[0022] 常见的感应区具有矩形二维投影形状,但也可能是许多其他的形状。 [0022] The common sensing region has a rectangular shape two-dimensional projection, but it could be many other shapes. 例如,根据传感器阵列和周围电路的设计,针对输入对象的防护,等等,感应区可能被做成具有其他形状的二维投影。 For example, depending on the design of the sensor array and the peripheral circuit, an input object for protection, and the like, the sensing region may be made into two-dimensional projections having other shapes. 类似的方法可W被用来限定感应区的=维形状。 Similar methods may be used to define W =-dimensional shape of the sensing region. 例如,传感器设计、防护、信号操作等等的任何组合,可有效限定延伸一段距离进出图1中的页的感应区118。 For example, any combination of sensor design, protection, operation signal or the like, which can effectively define a sensing region extend a distance out of the FIG. 1 on page 118.

[0023] 在运行中,输入设备116适宜地检测感应区118内一个或更多个输入对象(如输入对象114)。 [0023] In operation, the input 118 of one or more target input device 116 suitably detects the sensing region (e.g., 114 input object). 因此,输入设备116包含一传感器(未示出),其利用任何组合传感器元件和传感技术来实现一个或更多的感应区(如感应区118)并检测如对象的存在的用户输入。 Thus, the input device 116 includes a sensor (not shown), which sensor element and using any combination of sensing technology to implement one or more sensing regions (e.g., sensing region 118) and detects the presence of the user input as an object. 输入设备可W包含任何数量的结构,比如一个或更多的传感器电极,一个或更多的其他电极或者是适于检测对象的存在的其他结构。 W input device may comprise any number of structures, such as one or more sensor electrodes, one or more other electrodes or other structures adapted to detect the presence of the object. 作为一些非限制性的例子,输入设备可W使用电容的、 电阻的、电感的、表面声波和/或光学技术。 As a non-limiting example, W input device may use capacitive, resistive, inductive, surface acoustic waves and / or optical techniques. 运些技术中许多对需要移动机械结构(比如机械开关)的那些是具有优势的,因为他们可具有长得多的使用寿命。 Many of these transport technology is advantageous, because they can have a much longer service life for those who need to move mechanical structures (such as mechanical switch).

[0024] 例如,输入设备116中的传感器可W使用电容式传感器电极的阵列或其他模式来支持任何数量的感应区118。 [0024] For example, input device 116 may be a sensor or other mode using the array W capacitive sensor electrodes to support any number of sensing region 118. 作为另一个例子,传感器可W用电容传感技术,结合电阻传感技术来支持同一感应区或不同的感应区。 As another example, the sensor may be W capacitance sensing technology, resistive sensing technology to support binding the same or a different sensing region of the sensing region. 可用于实现本发明各种实施例的运些技术类别的示例可W 在美国专利号5,543,591,5,648,642,5,815,091,5,841,078 和6,249,234 中找到。 These exemplary techniques can be shipped category for implementing various embodiments of the invention W may be found in U.S. Patent No. 6,249,234 and in 5,543,591,5,648,642,5,815,091,5,841,078.

[0039] 现在转到图2和图3,其示出了感应区中的对象和作用力到表面的例子。 [0039] Turning now to FIG. 2 and FIG. 3, which shows the object in the sensing region and force to the surface of the Examples. 具体来说, 图2和图3示出了示例的输入设备200的俯视图和侧面图。 Specifically, FIG. 2 and FIG. 3 shows a top view of an example of the input device 200 and a side view. 在所示例子中,用户手指202和204 给设备200提供输入。 In the illustrated example, the user's finger 202 and 204 provide input to the device 200. 具体说来,输入设备200被配置成使用传感器在感应区206中确定手指202和204的位置。 Specifically, the input device 200 is configured to use a sensor to determine the position of the finger 202 and 204 in the sensing region 206. 例如,电容式接近传感器,采用多个传感器电极,可W被配置成通过检测在传感器电极间的跨电容式禪合的变化,来检测诸如手指202和204运样的对象,W及从已检测到的跨电容式禪合的变化来确定手指的位置。 For example, a capacitive proximity sensor, a plurality of sensor electrodes may be configured to change in W across the capacitive sensor Zen bonded between the electrodes is detected by detecting such a finger 202 and 204 of the sample transport objects, and from the detected W to cross the capacitive Zen change together to determine the location of the finger.

[0040] 根据本发明的实施例,输入设备200进一步地被配置成确定手指202和204作用到表面208的力。 [0040] According to an embodiment of the present invention, the input device 200 is further configured to determine the fingers 202 and 204 of the force applied to the surface 208. 具体来说,多个力传感器210被设置在感应区206各处。 Specifically, a plurality of force sensors 210 are disposed around the sensing region 206. 运些力传感器的每个提供手指作用在表面208上的力的一测量。 Each finger provides a force acting on the surface 208 of the force sensor of a transport of these measurements. 处理系统被配置成利用传感器确定的手指位置和力传感器210提供的力的测量确定单个手指202和204的每个作用的力。 The processing system is configured to determine the force acting in each individual fingers 202 and 204 using the measured force and the position of the finger force sensor determined by the sensors 210 provided.

[0041] 应该注意,被确定的力是被确定的多个手指中每个单独手指作用到表面208的力的总计。 [0041] It should be noted, the determined force is determined a plurality of fingers each individual finger surface 208 of the force applied to the total. 因此,系统可根据哪些手指按压W什么样的力做出不同的反应。 Therefore, the system can react differently depending on what kind of force which finger pressing W. 确定多个手指中每一个作用的力,W及响应于运样被确定的力提供不同的输入动作的能力,为帮助用户输入选择提供了广泛的灵活性。 Determining each of a plurality of fingers a force acting, W, and in response to the determined force is the ability to provide sample transport different input operation, provides wide flexibility to help a user input selection.

[0043] 如上所述,在本发明的实施例中,多个力传感器被设置到传感器周围并被配置成提供作用在表面的力的测量。 [0043] As described above, in the embodiment of the present invention, a plurality of force sensors are arranged around the sensor and configured to provide a force acting on the measurement surface. 运些单个的力传感器的每个都可WW任何合适的力传感技术实现。 These single operation force sensor may each be any suitable WW force sensing technology. 例如,力传感器可WW压电力传感器、电容式力传感器、电阻应变计和/或力感应电阻来实现。 For example, a force sensor may WW piezoelectric force transducers, capacitive force sensors, resistive strain gages and / or force sensing resistor is achieved. 此外,力传感器可W被实施成测量压缩力(即向传感器作用的力)、膨胀力(即离开传感器作用的力)、或者两者。 In addition, the force sensor may be implemented to measure W compressive force (ie a force sensor acting), the expansion force (i.e., away from the action of the force sensor), or both.

[0044] 力传感器被配置成每个提供向表面作用的力的测量。 [0044] The force sensor is configured to measure each of the surface to provide a force acting. 各种不同的实施都可W被用来帮助运一测量。 W various embodiments may be used to assist a transport measurements. 例如,力传感器中的传感元件可W是直接附着在表面的。 For example, the force sensor may be sensing element W is attached directly to the surface. 例如,传感元件也可W直接附着在表面的下面或其他层。 For example, the sensing element may be directly attached to a lower surface of W or other layers. 在运样的实施例中,凭借被直接禪合到表面,每个力传感器都可W提供对正在对表面作用的力的测量。 In an embodiment the sample transport, by virtue of being directly bonded to a surface of Zen, each of the force sensors can provide a measurement of W is the force acting on the surface. 在其他实施例中,力传感器可被间接禪合到了表面。 In other embodiments, the force sensor may be indirectly bonded to the surface of Zen. 例如,通过传递力的中间禪合结构,中间材料层或者两者。 For example, the intermediate laminated structure by Zen transmission of force, the intermediate material layer, or both. 不论哪种情况,力传感器又被配置成每个提供对作用到表面的力的测量。 In either case, the force sensor is configured to measure the force and the surface of each role to provide.

[0046] 总体上,把多个力传感器的每个设置在传感器边缘附近并最大限度地分开传感器将是理想的,因为运将易于最大化传感测量的精度。 [0046] In general, and apart from each of the plurality of force sensors disposed in the vicinity of the maximum edge sensor the sensor would be ideal, as will be readily transported to maximize the accuracy of the sensing measurements. 在大多数情况下,运将把传感器设置在靠近感应区的外缘。 In most cases, the sensor will be transported disposed near an outer edge of the sensing region. 在另外的情况下,其可能接近触摸表面的外缘,而感应区可W延伸出表面一定的距离。 In other cases, it may be close to the outer edge of the touch surface, and sensing region may extend a certain distance W surface. 最后,在其他实施例中,一个或多个传感器可能被设置在传感器内部。 Finally, in other embodiments, the one or more sensors may be disposed inside the sensor.

[0049] 转到图6,其示出了输入设备600的另一个例子。 [0049] Turning to Figure 6, which illustrates another example of the input device 600. 在该例中,四个力传感器610被设置在感应区606的周边内并在表面608的下方。 In this embodiment, the four force sensors 610 are disposed in the peripheral region 606 and beneath the sensing surface 608 in. 在该实施例中,力传感器610的每个都提供更大矩形区域上的力的测量。 In this embodiment, each force sensor 610 provides a measure of the force over a larger rectangular area. 该类型的传感器可W用力感应电阻或其他合适的设备来实现。 This type of force sensing resistors sensor W, or other suitable devices to achieve.

[0050] 本发明的实施例也适用于不同形状的输入设备。 [0050] Embodiments of the present invention is also applicable to an input device of a different shape. 转到图7,其阐明了输入设备700 的另一个例子。 Turning to Figure 7, which illustrates another example of an input device 700. 在该例中,=个力传感器710被设置在感应区706的周边内并且在表面708的下方,其中感应区706具有圆形的形状。 In this embodiment, the force sensors = 710 is disposed within the perimeter of the sensing region below the surface 706 and 708, wherein the sensing region 706 has a circular shape. 在运样的实施例中,传感器可W不同的坐标系来提供位置信息,如W极坐标。 In an embodiment the sample transport, the sensor may be a different coordinate system W to provide location information, such as polar coordinates W. 然而,在运种传感器中,直接或通过坐标转换,也可W提供XY坐标系的使用。 However, in kinds of sensor operation, directly or through coordinate conversion, W may also be provided using the XY coordinate system.

[0051] 应当注意,虽然图2-7阐明了很大程度上具有共同范围的各种感应区和表面,但并不是在所有实施例中都要求如此。 [0051] Note that although Figures 2-7 illustrate the various sensors and the surface region have a common range is largely, but not in all embodiments require so. 例如,在一些实施例中感应区的形状可能远远超出呈现给用户的主表面。 For example, in some embodiments, the shape of the sensing region may be presented to the main far beyond the surface of the user. 在另外的实施例中,也许刚好相反。 In further embodiments, maybe just the opposite.

[0052] 正如将在下文作更详细地解释的那样,输入设备的表面和其他层可W用具有不同物理性质的不同类型的材料来实施。 [0052] As will be explained in more detail below, the surface layer and other input devices may be W with a different type of materials having different physical properties to the embodiment. 例如,表面可W用具有不同物理硬度级别的材料实施。 For example, W can be a surface material having a different physical embodiment hardness levels. 因此,在一些实施例中表面可W随用户作用力而明显地偏转和弯曲。 Thus, in some embodiments, W may be a surface with a user force significantly deflect and bend. 在另一些实施例中,表面将拥有更大的硬度,因此在正常使用时可W很大程度地避免弯曲。 In other embodiments, the surface will have greater stiffness, thus during normal use can bend W largely avoided. 运些不同的实施可W 给用户不同的用户体验。 These different implementations may transport W user experience to different users. 例如,易于偏转给用户提供了与他们作用的力相对应的反馈的途径。 For example, users with a easy way to deflect the force and effect of their corresponding feedback. 通常,为了提供显著的偏转量,传感器可被配置W给感应层提供适当弯曲的空间的结构。 Typically, in order to provide a significant amount of deflection, the sensor may be configured to provide space W of the bent appropriately to the sensing layer. 例如,通过使用类似弹黃的结构。 For example, by using a structure similar to the spring. 此外,正如将在下文更详细地讨论的那样,用来确定感应区中多个对象中每一个的力的技术可适于说明使用过程中可能发生在表面上的偏转的总量。 Furthermore, as will be discussed in greater detail below, the techniques used to determine the force sensing region of each of the plurality of objects may be adapted to the total amount of instructions that may occur during use on the surface deflection.

[0053] 下面将不详细讨论可被用于确定感应区中多个对象的力信息的技术。 [0053] will not be discussed technical force information may be used to determine a plurality of objects in the sensing region in more detail below. 总体上,该技术利用通过传感器确定的每个对象的位置信息和力的多个测量来为每个对象确定作用力的总量。 Generally, the technique using the plurality of measured force and position information for each object is determined by the sensors to determine the total force for each object. 具体来说,该技术基于多个对象中每一个的位置信息利用力的多个测量的叠加来为每一个对象确定作用的力。 In particular, the technique to determine the force acting on the object for each of a plurality of superimposed plurality of measurement objects using the location information of each of the force. 在该实施例的一个实现中,此叠加通过伪逆矩阵技术来计算出。 In one implementation of this embodiment, this is calculated by superimposing a pseudo inverse matrix technique.

[0054] 作为一个例子,一输入设备可W被提供W四个力传感器,每一个都提供一力测量(尸化,。11^。6^。61〇。如上所述,输入设备被配置成使用例如电容式接近传感器的传感器确定多对象的位置信息。在本例中,感应区中的对象的位置用X和y坐标位置值来表示。因此,感应区中两个被检测到的对象的位置可W用值(xo,y日),(xi,yi)来表示。使用线性模型,并假设矩形传感器的尺寸是WxH,两个被检测对象(xo,yo),(xi,yi)的位置、四个测量到的力值(Ftl,Ftr,Fbl,Fbr),W及两个对象作用的力(Fo,Fi)之间的关系可W用矩阵方程表示为: [0054] As one example, an input device may be provided W W four force sensors, each providing a force measurement (Corprus, .6 .11 ^ ^ .61〇. As described above, the input device is configured to for example, a capacitive proximity sensor multi-object sensor to determine position information. in the present embodiment, the position of the object in the sensing region is denoted by X and y position values. Thus, the sensing region of the two detected objects W may be a position value (xo, y days), (xi, yi) is represented. using a linear model, and assuming that the size of the rectangular sensor WxH, two detected objects (xo, yo), (xi, yi) of position, four measured force value (Ftl, Ftr, Fbl, Fbr), the relationship between two objects and the force W acting (Fo, Fi) W can be represented by the matrix equation:

[0056] 方程1中的矩阵描述了具有两个未知数(即,两个对象作用的力Fo,Fi)的四个方程的集合。 In [0056] Equation 1 describes the collection of matrices with two unknowns (i.e., two objects acting force Fo, Fi) of the four equations. 此外,作用到传感器上的力的和等于测出的力之和。 Further, the force acting on the sensor is equal to the sum of the measured force. 因此,F〇+Fi = Ftl+Ftr+Fbl + F服D Thus, F〇 + Fi = Ftl + Ftr + Fbl + F D clothing

[0057] 输入设备的处理系统可适于解出运两个未知量,并且因此确定运两个输入对象作用的两个单独的力。 [0057] The processing system input device may be adapted to solve for two unknowns shipped, transported and thus determining two two single input action of the object. 具体来说,方程1可用简写矩阵的形式被写成: Specifically, the matrix forms can be abbreviated written as Equation 1 is:

[0059] 其中X是包含待求解力元Fo, Fi的矩阵。 [0059] wherein X is a force element to be solved Fo, Fi matrix. 此矩阵方程的伪逆关系可W被表示为: This pseudo-inverse relationship W matrix equation can be expressed as:

[0061] 因此,使用伪逆矩阵技术,处理系统可W求出两个对象的力值Fo, Fi。 [0061] Thus, using a pseudo inverse matrix technique, two processing system may determine the object W force value Fo, Fi. 具体说来,伪逆矩阵技术(有时叫做广义逆技术)提供一种可W用来通过最小化解中的误差来解出其中方程多于未知数的超定系统的技术。 Specifically, the pseudo-inverse matrix technique (sometimes called generalized inverse technique) to provide a W techniques used to solve an overdetermined system wherein equations than unknowns resolved by minimizing errors. 在一些实施中,此技术被配置成最小化全局误差。 In some implementations, this technique is configured to minimize global error. 在其他实施中,此技术被配置成至少最小化均方误差。 In other implementations, this technique is configured to at least minimize the mean square error. 不论哪种情况,伪逆矩阵技术最小化误差W提供运个方程组的解。 In either case, a SLM equations pseudo inverse matrix W provide a technique to minimize the error. 应当注意伪逆矩阵技术只是各类可用技术的一个例子,并且总体上,可W使用任何能被用于解出超定系统的技术。 It should be noted that the pseudo inverse matrix technique is just one example of various types of technology available, and generally, any technique can be used for W surplus solution given system.

[0062] 因此,处理系统可接收两个对象(XO,yo),(XI,yi)每一个的位置信息,四个已测出的力值化1听川8川81〇,并^此确定两个对象发每一个正在作用的单个力航,尸1)。 [0062] Thus, the processing system may receive two objects (XO, yo), (XI, yi) of the position information of each of the four force values ​​have been measured of a plain plain 81〇 8, and this determines ^ two objects are each made of a single acting Air force, P 1).

[0063] 运样的系统也可W解=个对象作用到表面的力(Fo,Fi,F2)只要运=个对象是非共线排列。 [0063] The system may also sample transport solution W = force applied to the object surface (Fo, Fi, F2) = transported long objects arranged in a non-collinear. 在那个例子中,矩阵方程: In that case, the matrix equation:

[0065] 定义了将要确定的由=个对象作用的力(的方1,。2)。 [0065] defined to be determined by the force acting = object (square 1, .2). 此矩阵方程描述了具有=个未知数的四个方程的集合,并且处理系统可适于利用与前述相同的伪逆关系求解那些未知数。 This matrix equation describes a set of equations having four unknowns =, and the processing system may be adapted by the same pseudo-inverse relationship with the solving these unknowns.

[0066] 运些示例提供了确定感应区中两或=个对象作用的力的能力。 [0066] These exemplary operation provides the ability to determine the force sensing region two objects or action =. 应当注意,虽然运些示例描述使用包含四个力传感器的系统求出力值,类似的技术也可W被应用于具有不同力传感器数量的系统中。 It should be noted that, although some examples describe the use of transport system comprises four of the force sensor output demand value, similar techniques can also be applied to a number of different W force sensor system. 通常,每个额外的力传感器提供额外数据,其可W被用来确定力。 Typically, each additional data to provide additional force sensor, which can be used to determine the force W. 因此,更多的传感器增加了可W用来生成解的方程的数目。 Thus, additional sensors may be W increases the number of solutions to equation generation. 和上述相同类型的技术因此可W被用来解运样的超定系统,通常使确定的力具有更高的精确度。 And said same type of technology can thus be used to solve overdetermined W sample transport system, usually a force determined with higher accuracy. 此外,使用更多数量的传感器可在传感器发生故障时提供冗余。 In addition, a greater number of sensors may be used to provide redundancy in case of sensor failure.

[0067] 如上所述,输入设备可W用各种不同的材料来实施,包括具有不同硬度级别的表面材料。 [0067] As described above, the input device may be a variety of different materials W to embodiments, the surface comprises a material having a different hardness levels. 在表面材料被配置成可W随作用的力而显著弯曲和偏转的实施例中,系统可被配置成可W解释那些偏转。 The surface of the material is configured to be a force W acting with significantly bent and deflected embodiments, the system may be configured to be W explain the deflection. 运可W带来对运些实施例中作用的力更精确的确定。 Yun W can lead to more accurate determination of these transport force acting Example embodiment.

[0068] 作为一个例子,输入设备可再被提供W四个力传感器,每个提供力测量(Ftl,Ftr, Fbl,Fbr)。 [0068] As an example, the input device may further be provided W four force sensors, each of which provides a force measurement (Ftl, Ftr, Fbl, Fbr). 感应区中两个被检测到的对象的位置被再次由传感器确定并被表示为位置值(X0, y〇),(xi,yi)。 Sensing region two object position is detected by the sensor is again determined and expressed as a position value (X0, y〇), (xi, yi). 假设表面的偏转是对作用力的响应,并再假设矩形传感器的尺寸是WxH,两个被检测到对象的位置(xo,yo) , (XI ,yi),四个被测出的力值(Ftl,Ftr,Fbl,Fbr),W及运两个对象作用的力(Fo,Fi)之间的关系可W用矩阵方程表示为: Suppose deflection surface in response to the force, and further assume that the rectangular sensor size WxH, two detected object position (xo, yo), (XI, yi), four out of the measured force value ( Ftl, Ftr, Fbl, Fbr), the relationship between the two objects and migration force W acting (Fo, Fi) W can be represented by the matrix equation:

[0070] 矩阵方程5再次描述了具有两个未知数(即,由对象作用的力Fo,Fi)的四个方程的集合。 [0070] Equation 5 again describes matrix having a set of two unknowns (i.e., the target acting force Fo, Fi) of the four equations. 运两个未知数可W再用伪逆矩阵技术或任何其他适于解出超定系统的技术来解出。 W may be transported again two unknowns pseudo inverse matrix technique or any other suitable technique surplus solution to solve a given system.

[0073] 限定要被确定的S个对象作用的力(。〇术1,。2)。 [0073] The force S is defined to determined the effect of objects (1 .〇 surgery, .2). 该矩阵方程描述了具有^个未知数的四个方程的集合,而处理系统可适于利用与前述相同的伪逆关系求解运些未知数。 This matrix equation describes a set of equations with four unknowns ^ and the processing system may be adapted to use the same pseudo-inverse relationship with the transport solving these unknowns.

[0074] 方程5和6中定义的关系同样可适于具有不同数量、形状W及力传感器的配置的传感器。 [0074] Equations 5 and 6, the relationship may be defined in the same sensor having a configuration adapted to a different number, shape, and W is a force sensor.

[0075] 当如此确定时,力的值可W被用来帮助许多用户界面功能性。 [0075] When the thus determined value of the force W may be used to help many user interface functionality. 如上所述,系统可W 被用来使能基于力和接近指示的任何类型的用户输入。 As described above, the system may be used to enable input W based on the force and any type of proximity indication of the user. 例如,对多个对象的力和接近的持续测量可W被用于扩展放大,滚动或旋转。 For example, a plurality of force and proximity to objects W can be used for continuous measurement extended amplification, rolling or rotation. 其也可W被用于虚拟键盘应用和按压W选择手势。 It can also be used for the virtual keyboard application W and W is pressed to select gestures.

[0076] 在运些实施例的变化中,力传感器提供的力的测量也可W被用来消除对象位置的模糊性。 [0076] In some embodiments the change operation, the measurement of the force provided by the force sensor may be used to eliminate ambiguity W target position. 具体来说,在一些类型的传感器中,感应区中出现的两个对象会导致对象位置模糊。 In particular, in some types of sensors, two objects appearing in the sensing region can result in blurred object position. 在使用被配置成生成一维轮廓W及从运些一维轮廓中生成对象位置的电容式接近传感器的输入设备中运是一个典型的问题。 In use configured to generate a one-dimensional profile of the object W generated from the position and operation of these one-dimensional profile of the capacitive proximity sensor operation input device is a typical problem.

[0077] 转到图8,其示出了示例的输入设备800。 [0077] Turning to Figure 8, which shows an example of the input device 800. 输入设备800包含了一传感电极阵列803 W及四个力传感器Fl,F2,F3和F4。 The input device 800 includes an array of sensing electrodes 803 W and four force sensors Fl, F2, F3 and F4. 同样示出的是可从电极803的感应区中存在的两个对象生成的X和Y坐标轮廓801。 Also shown is the presence of two objects from the sensing region of the electrode 803 in X and Y coordinates generated contour 801. 如图8所示,单WX和Y坐标轮廓数据,存在关于两个对象是在位置802或位置804(图8中用楠圆虚线示出了可能的位置)的模糊,因为任何一个选择都会带来同样所示的X和Y坐标轮廓801。 8, WX and Y coordinates of the single contour data, regarding two objects are present at a position 802 or position 804 (dotted line circle in FIG. 8 by Nan shows a possible location of) blur, because any choice will bring a to X and Y coordinates 801 as shown in the same profile.

[0078] 在该实施中,由力传感器Fl - F4提供的力的测量可W被用来消除对象位置的模糊性。 [0078] In this embodiment, by the force sensor Fl - F4 provide a measurement of the force W may be used to eliminate the ambiguity of the position of the object. 具体说来,因为越靠近对象,传感器上的作用力越高,力的测量可W被用来确定对象实际位于两个位置中哪一个。 Specifically, since the closer the object, the higher the force sensor measuring the force W may be used to determine the actual object which is located in two positions. 例如,如果力传感器Fl和F3测量到的力明显大于传感器F2和F4 的,运就表示对象很可能在位置802。 For example, if the force sensors Fl and F3 is significantly greater than the measured force F2 and F4 of the sensor, it means the object is likely to run in the 802 position. 反之,如果力传感器F2和F4测量到的力明显大于传感器Fl和F3的,运就表示对象很可能在位置804。 Conversely, if the force sensor F2 and F4 significantly greater than the measured force sensors Fl and F3, the operation is likely to represent the position of the object 804. 因此,力的测量可W被用来消除两个对象位置的模糊性。 Therefore, measuring the force W may be used to disambiguate the two object position.

[0079] -旦对象位置的模糊性被消除了,每个对象的单个力的值就可W像上述那样被计算出。 [0079] - Once target position ambiguity is eliminated, the value of each single force object W can be calculated as described above. 因此,来自力传感器的测得的值可W被用来消除对象位置的模糊性,W及通过确定的对象位置,来确定每个单独对象作用的力。 Thus, the measured value from the force sensor may be used to eliminate ambiguity W target position, W, and by determining the object position, the object to determine the effect of the force of each individual. 利用力传感器来消除模糊性,可W顾及使用低成本的轮廓传感器,其否则在某些情况下无法消除多个手指位置的模糊性。 To eliminate ambiguity, W may take into account the use of low-cost profile sensor or in some cases can not disambiguate multiple finger positions with the force sensor.

[0080] 因此,本发明的实施例提供了设备和方法,其从感应区中多个对象中每一个的位置信息W及力信息二者来帮助确定用户输入。 [0080] Thus, embodiments of the present invention to provide an apparatus and method which from the plurality of objects in the sensing region of each of both the location information W and force information to help determine the user input. 在运些实施例中,处理系统被配置成确定感应区中传感器感应到的多个对象中每一个的位置信息。 In some embodiments, operation, position information processing system is configured of a plurality of objects detected by the sensors sensing region in each to determine. 此外,处理系统还被配置成从作用到表面的力的位置信息W及多个测量确定多个对象中每一个的力信息。 In addition, the processing system is further configured to force information of each of the plurality of objects is determined from the force applied to the surface W and the position information of the plurality of measurements. 因此,此设备和方法提供了确定感应区中多个对象中每一个的位置信息和力信息二者的能力。 Thus, this provides a method and apparatus to determine a plurality of objects in the sensing region of each of the capabilities of both the position information and force information. 运可W用来帮助提高用户界面功能性,例如,通过规定特定的用户界面动作来响应对多个对象的力的确定的指示。 W may be transported to help improve the user interface functionality, e.g., in response to an indication of the force is determined a plurality of predetermined objects by specific user interface action.
